Nissan 350Z front and rear side marker bulbs utilize a 168 bulb size across both locations. The replacement chart covers vehicle production spanning 2003 to 2005.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The 168 bulb is the sole bulb type specified for the Nissan 350Z across all listed side marker positions and model years.
The 168 bulb follows the ANSI standard recognized in the United States and Canada, classifying it as a region-specific designation rather than a universal international one.
It belongs to the T10 miniature wedge form factor, a base style that requires no locking mechanism, as the wedge shape of the glass envelope itself secures the bulb within the socket.
The bulb operates at 12 volts, consistent with the standard electrical system voltage found in conventional passenger vehicles.
Its rated wattage of 4.9W places it in the low-power range typical of marker and clearance lighting, where continuous illumination is required without significant heat output.
The Nissan 350Z (2003-2005) uses the same 168 bulb specification for both the front and rear side marker positions, indicating full interchangeability between those two locations on the vehicle.
